WordPress 2.0: Hide post preview
Published Tuesday, January 3rd, 2006 at 8:44 am
If you're using WordPress 2.0 you may notice one of the cool new features is the post preview. When you save a post or edit a post down at the bottom of the post page you are presented with a preview of your post. This preview shows the whole page (not just the post text), logo, navigation, everything that is on the main page. I really like this feature but I don't always want to use it. Most of the time I don't need to look at it. For example when making a simple change. So it is just a waist of bandwidth and server power. If you read my blog regularly I'm sorry you know that I never just accept these types of things. So I modified the

If you are using WordPress version 2.1 then you should replace line 72 in
Preview is no longer inline so this change is not needed.
/wp-admin/post.php file to allow me to view the preview only when I need it. I considered making this a plugin but as far as I can tell there is no way of preventing the preview page from loading via a plugin. I could easily hide it but the data will still be pulled from the server. So if you would like to make the changes yourself open /wp-admin/post.php and find line 85
<iframe src="<?php the_permalink(); ?>" width="100%" height="600" ></iframe><script type="text/javascript">
<!--
function show_preview() {
var elm = document.getElementById("frm_preview");
elm.src = "<?php the_permalink(); ?>";
elm.height = "600";
return false;
}
-->
</script>
<a href="#preview-post" onclick="show_preview();">Show Preview</a>

Thanks, I’ve been looking for this for the reasons you cited as well as not wanting my adsense account to be confused by being asked to be shown in the preview pane when they are not even posted on a real url. Good work

Google Adsense and Wordpress 2.0: beware of the preview
Wordpress 2.0 has a preview feature that can cause Adsense problems:
“… because the post hasn’t been published yet, when Google’s bot tries to crawl the page a few seconds later, it will receive a 404 error.”
Google pr…

Tim,
Thanks for the comment. I hadn’t thought of the adsense issue. Also check out Lunacy Unleashed for a way to disable adsence inside the preview page (found via the trackback on Jan. 30).

[...] By far my favorite are the hacks, fixes, and tips. The posts are where something wasn’t working or wasn’t working the way I wanted so I fixed it. I’ve always been doing these type of things but finally I found a medium to efficiently share my experences. I feel quite satisfied being able to share these with others. These also end up being my most popular posts. One example is a fix for a WordPress 2.0 bug that prevented WP from running on windows machines (fixed in WP 2.0.1 version thanks to my bug report). I shared my method for hiding the WordPress post preview. I discovered a fix for a problem debugging Visual Studio applications with .NET 2.0 runtime installed. I also used my blog to spread the word of my first Firefox extension. [...]

Nice hack!
This really should be a default option…

hey, thanks for the pointer. I had a similar hunch and landed up on this page via google. What I want to know is that if you remove that block from the post.php file, the preview iframe will not be displayed, but will the data still be pulled from the db, and more importantly, since we’re not displaying it, i guess the googlebot will not try to crawl over, because the ad will not even be displayed ?? is that correct, or …

saurab,
If you do not hit the “show preview” link the preview will not be pulled from your sever. The google ad will not be pulled form the server and everyone will be happy.

Arggh thank god someone has fixed this – has been driving me mad! I agree it should be changed to the default option

The 2nd code works perfectly in my WP 2.0.4.
Thnks.
By the way, to hide the adsense in preview mode I’m just inserting the adsense code between an
!is_preview() IF.

The code in WP 2.0.5 is different around line #82 in /wp-admin/post.php:
<div id=’preview’ class=’wrap’>
<h2 id=”preview-post”><?php _e(‘Post Preview (updated when post is saved)’); ?> <small class=”quickjump”><a href=”#write-post”><?php _e(‘edit ↑’); ?></a></small></h2>
<iframe src=”<?php echo wp_specialchars(apply_filters(‘preview_post_link’, add_query_arg(‘preview’, ‘true’, get_permalink($post->ID)))); ?>” width=”100%” height=”600″ ></iframe>
</div>
So, the change you made won’t work. Any fixes? Please email it to me at [tbond] at [ideapro.com]. We’re installing the changes on http://www.partnershipinparenting.com/
Thanks for your help!

Hi all!!! Cool site!!!
January 8th, 2007 at 8:42 am
Line 84 in Wordpress 2.0.6 !!

Yes, unfortunately it has to be reinstated every time there is a new version. I usually run a diff on this file before every upload. Combine these lines with the rest of the new file. This feature has been submitted to the WordPress tracker but it is classified as a new feature and therefore will not show up in the root until 2.1.

See the update above for version 2.1. This enhancement has now been delayed to 2.2.

Perfect. For some reason, some of my sidebar widgets have been slow loading. When the preview pane was active, this slowed down loading of articles for me to edit. Your change is exactly what I needed to speed up loading the page to write or edit while still keeping preview functionality. Hope this gets in the official release soon.

Thank you so much for posting this code change. The preview was slowing me down, big time. Thanks again!

Thanks a lot! You rules!

perfect!! nowadays… with so many widgets and remote scripts, disabling the preview is a real time saver!! thanks mate!!
